Another purpose is to provide an improvedhot water Vheating member or assembly for use with hydroxylating pot Wpe burners.

Another purpose is toprovide a burner assembly, including av pot typeburner and a heating member which is Yadapted at the same time to heat water and to serve as aflamefring for the pot. p

Another purp'os'eis t'o provide animproved flame ring which may be applied to a pot and which includes af water heating component. y Another purpose is to provideaheat exchanger which., can be applied as an integral partr of va burner, such as a pot type burner, and? which picks up, and employs what would otherwise; be waste h`eat.v

Other pur-poses will appear fromftime to' tiniein the course of the specication and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings where- 1n:

soiaims. (o1. 1269350?) f Figure 1 is a section taken on the axis of the 7 burner pot;

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a section on the line 3-3 of Figure 2; and

Figure l is a diagrammatic side elevation on a reduced scale illustrating the device in connection with a hot water system.

Like parts are indicated by like symbols throughout the specification and drawings.

Referring to the drawings, I generally indicates the side wall of a burner pot and L2 the closed end wall of such a pot. The pot is herein illustrated as a so-called horizontal pot in which the axis of the pot is horizontal. It will be understood that this is a matter of illustration, and that our invention may be applied to burners wherein the axis is other than horizontal such as burner pots having a vertical axis. The burner pot is shown as having a top or end ange 3, adjacent the open end of the burner. 4 indicates a generally cylindrical outer housing having an end 5 centrally apertured as at 6 to receive any suitable booster fan assembly l, the details of which do not form part of the present invention. 8 is a vaporizing cup, located within the burner any'n suitable duct 'SIr` extending t'ov-l any suitable sourcefof liquid fuel not herein shown;v Therate of: flowf' of liquidl fuel alongv the duct' 9 may be' cont-rolled byy anyv suitable valve means herein shown as'A Ill'. It will be understood' that we'inayt employ-Y a conventional float valve or any other means' for controlling the rate ofv liquid: fuel ilowi As a matter of illustration; however, weillustr'ate a' valve-,including a manual valve controllingmemberfll. If a vertical'- axisedpot is: used', the fuel: may be supplied4l to the bottom of the pot.

'lfzgenerally indicates a watenheating assembl'y'andcombined flame ring. It is shown as in# cl'udinga front plate' I3I which maybe centrally apertured as` at ISG" and' has an inner flangev I5 and' isoutwardlycontinued by'mean's of an inner side wall I6, a wall I'l, and an out'ersi'de Wall' i8, to forma circumferentially extending, duct. The space between the flange "I 5f and the wall" I is adapted to receive the endv portions ofthe pot I` and the outer cylindrical housing 4I, the parts beinfeecured by' any'suit'able screws 20' extending through' apertures 2l' in the plate ISL '22 and 23 'are duct extensions, either of which may serve as an inlet duct or an outlet duct, depending upon the desired direction of flow of the Water or other lluid being heated. The assembly may be secured in connection with any suitable water storage tank diagrammatically indicated at'24, to which the duct may be secured in circuit by any suitable pipes 25 and 26.

It will be realized that, whereas, I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disposition of parts Without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.

The use and operation of the invention are as Y follows:

In hydroxylating pot type burners which We have developed in the past, we employ a pot, such as the pot I, having Va circumferential side wall provided with a plurality of primary air inlets 50 Y and vaporized fuel moves toward the open end of the pot. `There it may receive a secondary supply and supplied with any suitable liquid fuel through of air from the secondary air inlets 5 I. We may employ a variety of such inlets, but for convenience we illustrate a single row of inlets, somewhat larger than the primary air inlets 50, somewhat more closely spaced and having axes inclined toward the central aperture I4 of the ame ring component I3 of the heating assembly. When a maximum supply of liquid fuel is delivered for vaporization to the cup 8, and when the booster motor 1 is operating, there is a substantial ow of ame against the inner facepf the ring:v I3vand through the aperture I4. Thisame extends into any suitable combustion chamber 55, the detailsv of which do not form part .of the present invention. We employ this flame, without perceptible loss of heating effect, to heat water 'circulating through the duct dened by the walls I3, I6, Ii,

and I8. The flame ring component I3 is shown` as integral with the Water-carrying duct. This is advantageous, but is not an absolutely necessary arrangement. A separate ring portion in adequate heat transfer relation with the duct may be employed. By employing a Well insulated storage tank 24 in circuit with the duct, cold wafter from the bottom of the tank may circulate to the duct for heating and water heated by the duct is returned to the top of the tank. Thus, in the normal operation of the burner a tank of substantial size may be kept adequately heated. The`V burner unit may be secured to the combustion chamberlelement 55 by bolts 60 which extend through apertures 6I in the combined amerng and water heating structure I2.

Whereas we have shown our invention as applied to a hydroxylating pot type burner in which a liquid fuel is vaporized ina burner pot, it will be understood that our invention may be applied to other burners and may be used with other fuels such as. gas.

, We claim:

1. In combination a pot type burner having an open mouth, a. flame ring partially closing the mouth'thereof, a water chamber in the outer periphery of the ring encircling and entirely outside of the mouth of the burner, conduits connected to the chamber adapted to permit water circulation therethrough.

2. In combination a pot type burner having an open mouth, a flame ring partially closing the mouth thereof, a water chamber in the outer periphery` of the ring encircling and entirely outside of the-mouth of the burner, conduits connected to the chamber adapted to permit water circulation therethrough, the burner having a periphery of secondary air inlet apertures in the wall thereof adjacent the open mouth, that position of the flame ring which contains the water chamber being bounded on the side furthest from the plane of the open mouth by the plane passing through and deiined by the inlet apertures.

3. `In combination a pot type burner having an openmouth, a housing supporting the burner and containing a combustion chamber in register with the burner, a iiame ring partially closing the mouth of the burner and interposed between it and the combustion chamber, a water chamber inithe outer periphery of the ring encircling and entirely outside of the mouth of the burner and entirely outside of the combustion chamber whereby water in the chamber is heated entirely by heat conducted from the inner position of the llame ring across the pot mouth to the water chamber.
